使用GxEPD2库的第一步是配置ePaper连接,指定将哪些微控制器引脚分配给各种控制信号。在这种情况下,我们需要定义BUSY, RST(复位),DC(数据/命令),CS(芯片选择),SCK(串行时钟)和MOSI(主输出,从输入)信号。 幸运的是,Elecrow已经在他们的存储库中分享了该面板的原理图,使得检查和识别ESP32上连接到这些信号的引脚变...
Question:When testing the program, the program keeps stuck on an e-Paper busy? Answer: It may be caused by the unsuccessful spi driver 1. Check whether the wiring is correct 2. Check whether the spi is turned on and whether the parameters are configured correctly (spi baud rate, spi ...

1) BUSY: BUSY signal of e-paper. When the e-paper is refreshing, the BUSY pin sends out "busy" signal to MCU, the MCU can not read and write the e-paper IC; When the e-paper refresh is completed, the BUSY pin sends out "free" signal, the MCU can read and write the e-paper...
摘要:在互联网、5G、大数据等技术快速发展的背景下,传统零售业向新零售模式转型是必然趋势,而电子纸价签则是传统零售业转型道路上的刚需品。ePaper Insight 预测,2022年全球电子价签整机市场规模增长迅猛,预计市场规模将接近30亿美金。 2016年“新零售”概念被首次提出,新零售业态门店也随之应运而生。到如今,人们已经...
